I grow this plant (a male) espaliered against one side of my house, and enjoy its showy variegated leaves (green with white and a bit of pink) in the early season. The color is only in the male, I believe, and once summer heats up it fades. I have found kiwi pretty resilient…but not if it’s not up and growing! Sounds like one plant may not have survived. As for the long branch of the female, you can cut it back a little now (not sure how long it is, but don’t cut it way down). I save most of my pruning for very early spring, once I see what winter does to the thing and where new growth wants to happen. One thing I do before winter, however, is make sure the existing stems are secured to the trellis so they don’t go whipping around. Sometimes this involves cutting out unwanted stems altogether that are badly placed and don’t fit into the architecture of the plant, but you don’t have that situation yet.
